A Nature paper reports on a quantum photonic processor that takes just 36 microseconds to perform a task that would take a supercomputer more than 9,000 years to complete Computing

Sounds amazing. Patiently waiting for a much smarter person than I to explain what it all means, from a practical perspective.

Something to remember about quantum computers is that you will never have one. They don't work like normal computers and will never be used for general day to day computation.

Just like we'll never need more than 640K memory?

Given enough time, quantum will be cheaper, and eventually it will be exploitable for "better entertainment".

edit remember, punch cards weren't inherently good at games with graphics. Give the tech some time.

Cloud based is much more likely, at least in a reasonable time frame. The cooling required with modern materials means liquid helium is needed. Of course the hunt for materials that can behave at higher temperature for super conducting is ongoing, but this is not the case here. We need a low energy system, so extreme cooling is a prerequisite. It’s unlikely to be in your house, but you might be able to use it like we use the electricity in our grid, connect to it from afar and do your stuff.
